Arnold Schwarzenegger has been making headlines lately for his Hollywood comeback, but today, it's for sadder reasons: the former Governor and his wife Maria Shriver have announced their separation after 25 years of marriage. An unfortunate situation to be sure, but leave it to the celebrities of Twitter-Wood to find jokes in the midst of tragedy.

Excepting Arnold and Maria's breakup, the focus amongst film stars and writers on Twitter is fairly scattered today. One comedian has a reminder about The Lonely Island's new album, while another reflects on how little the world has changed in light of Osama bin Laden's death.

Osama Reflections: @SethMacFarlane Just spilled coffee, got a parking ticket and misplaced my cell phone. Thought Osama’s death would put an end to all that s***.-Seth MacFarlane, writer ("Ted," "Family Guy")

Tarantino Dream-Casting: @sutterink my secret dream is to be cast in a tarantino film as an imaginative malevolent psychopath with a good heart... ya know, play myself.-Kurt Sutter, writer ("Sons of Anarchy," "Southpaw")
